Non-toxic glue would be starch or gelatine - both used as base of some ‘real glues’, both with valid culinary use, including exactly this use case. We just don’t call those ‘glue’ in this context.

Not that easily and cheaply as they used to be.

Doesn’t sound like the ‘cheap small computer you can run your hobby electronics project on’ that the original Pi used to be. It is not as cheap and a power hungry beast, still small, though. More and more like a PC and less and less a small cheap embedded platform. For some people it is a plus (I guess for most people here), for some not so much.

I tend to build my projects on Raspberry Pi Pico now, but sometimes I would need something more powerful and Raspberry Pi 5 will be too much.

Jira was ok until they dropped self-hosting option. Why should I keep internal development data at third party server?

Other Atlassian software, though… oh, what a mess. And it only was getting worse with any new release. I am glad we have dumped it all.

I know Restic before Kopia and made a set of systemd units to run Restic backups on my home server and office workstation (both online 24/7).

Kopia seems much nicer for a regular user, so I use it on my and family laptops. I used to use Duplicati there, but that project seems dead.

Restic or Kopia, both to Backblaze.

Raspberry Pi is based on smart phone chips, very specific chips from one manufacturer. Raspberry Pi Foundation is not the main customer for this manufacturer and chips used for Raspberry Pi are not their only product – and now, during the big ‘chip shortages’ and supply chain problems other customers and other chips are given priority. There are no (or not enough) new chips for Raspberry Pis so there are no new Raspberries, so availability is dropping and prices are soaring.

I guess the same is true for most other SBCs.

For my hobby projects I switched to Raspberry Pi Pico. It is not a SBC, you won’t run Linux on that, but it is a very capable microcontroller board which is enough for my needs. It is way cheaper much more available. And I won’t look back – it occurred to me that things are much simpler when there is no whole OS on my devices and everything the device does is in my own code.

There are no problems with Pico availability, as it is based on a simpler, custom chip, designed by Raspberry Pi Foundation and manufactured for Raspberry Pi Foundation – they are no longer dependent on a single supplier.

Photos already took place of another application killed by Google. It can be killed again.

Before SteamOS could become a thing Valve made HUGE effort to make Linux useful for gaming. All the games everyone can now easily play on any x86 Linux distribution - that was possible, in a big part, by Valve efforts. Driver improvements, compatibility layers (not just Proton, but also improvements in the upstream wine), etc.
And they do continue the improvements, not just for their own Linux systems.
